This inventionrelates toihovers and has for its principal object the .pr'ovisionso'f a conical hover which maybe heated by hot wateror by steam and in which the l ventilation is improve.d. .sothat the "5 crowding ofthe chicks islminimized.

In hoveiicon'struction the public. has become accustomed to' the conical .shapeland while (this shaperi's' not as reflective as otherfshapes its popularity makes. it essential that manufacturers pro- .duce atrle'astlone' model; oflthis type.- It is simple indeed toiheatlavconical hover if. a flexible xperipheral wall the usedto 1:01am theain While this works satisfactorily in some ways itlhas many inherent. disadvantages,and the production of the requisitelheat inithehover while still having plenty ofventilation is'a problemvwhich heretoforelfhas notbeen -.'satisjfactorilyisolved. Onerequire'ment'is' that 'the heat be not confined to the radiating surfaces for. it is easily possible otherwise to ,have 'the' condition arise wherein these chicks nearest to the heating lelementare" kept sufficiently warm whileiother. chicks areso chilled as to cause fatality. i'Th'e present .hover piping is so located that oneat leastof thepipes. creates a 'zone of high temperature against the wall of the houseeso as, to prevent crowding .of the chicks toward thel'darker rear oftheenclosure.

tank- 15.

4. The more sharply tilted arms 32 discharge into the lower chamber 18 which also receives a quantity of hot water thru the by-pass opening 19. The return pipe 22 and the return main 24 obviously lead to a heater which is not shown.

Referring now particularly to Figure 3 which is a sectional elevation thru a poultry shed or house showing the relative location of the hover and the rear wall; The space toward the rear wall 46 is naturally darker and the chicks fre quently crowd into this darkened corner which,

normally would be considerably colder than under the hover and because of the coldness the chicks crowd to an improper degree. This I avoid by placing the return pipe 24 in the cornerand if I use a vapor line the inlet main 47 is placed just above the return line 24 and over'both I place a slanting screen of wire gauze 48 to prevent access.

The return pipe.24, or both pipes as illus-.- trated, create a zone of high temperature against the rear wall 46 of the'house and this entirely obviates crowding of the chicks at thatpoint since there 'is plenty of heat in that zone. With the vapor line I may use a vertical pipe 44 and a substantially horizontal pipe 45 to lead to the L 11 but in case I use hot water I must place the inlet main at a higher elevation as "will be readily understood.

While it is not at all essential so to do I prefer to have the height of the cylindrical casing 28 such that in the lowest position of the cone 26 the sloping pipe sections 32 will rest upon this annular wall and I also mayextend the air intake 25 thru the screen 48. While it would be better theoretically to make the tubes 30 of copper I do not flnd it advantageous from a practical standpoint to use this more expensive material and in my recent output I have used iron pipe 30 and weld them into the tank and I also find that I can weld in the caps or disks 14 just as conveniently and cheaply as to provide caps which-have threaded engagement with the tank walls; furthermore bythus welding all of these parts together I secure a much longer troublefree life for the device.

The construction shown is an improvement over the provision 'of a solid radiating element as'by virtue of the radial disposition of the tubes 30, a plurality of spaces are provided for the circulation of theair, and the chicks on the ground are warmed by direct radiation from the upper arms 31, as well as from the lower arms 32in just the same way that sensible heat is directly radiated from an old' fashioned hearth. In addition, the lower surface of the disk.34 and its integral downwardly turned flange are polished in order to reflect downward the heat radiated from the upper arms 31 of the tubes.

There is naturally a blanket of hot air formed beneath the ceiling wall of the cone, and this discharges annularly about the edge 45 of the cone, but upward radiation from the pipes 32 is not lost as it would be in a solid element, because not only can the pipes radiate directly down but the upper radiation is reflected down to the ground by the mirror bottom of the disk 34, which it will be noted somewhat snugly fits the pipe and with the collar 40 serves to The fresh air is delivered centrally and is warmed not only by radiation from the disk 35 but by contact with the tubes'or pipes 30 and by the body of the What I claim is:
